16 – SS P-Lube Oil
Cause
Corrective action
The lube oil pressure measured at
sensor B5.1 has violated limit
value 2. The lube oil pressure is
too low.
1. Check engine oil level (→ Page 112).
2. Contact Service.
19 – HI T-Exhaust A
Cause
Corrective action
The exhaust gas temperature
measured at sensor B4.21 has
violated limit value 1. The exhaust
gas temperature is too high.
u
Contact Service.
20 – SS T-Exhaust A

21 – HI T-Exhaust B
Cause
Corrective action
The exhaust gas temperature
measured at sensor B4.22 has
violated limit value 1. The exhaust
gas temperature is too high.
u
Contact Service.
22 – SS T-Exhaust B
Cause

23 – LO Coolant Level
Cause
Corrective action
The coolant level in the high-
temperature circuit measured at
switch F33 is too low.
1. Check engine coolant level (→ Page 116).
2. Check relief bore of engine coolant pump (→ Page 122).
3. Visually inspect cooling circuit for leakage.
4. Contact Service.
